DETAILED DESCRIPTION

While a number of examples have been described for illustration purposes, the foregoing description is not intended to limit the scope of the invention, which is defined by the scope of the appended claims. There are and will be other examples and modifications within the scope of the following claims.

A puzzle is a toy or game designed to challenge a person’s cognitive abilities and problem solving skills. A puzzle has a rigid frame with two opposite sides. Each side has multiple recesses. A set of pieces fit the recesses. The recesses of each side of the rigid frame are sized to simultaneously accommodate all of the pieces of the set and make an arrangement of the pieces.

FIGS. 1A, 1B, 2A, 2B, and 3 show a children’s puzzle 100 having a rigid frame 102 and a set of removable, rigid, non-interlocking pieces 106 that fit in recesses 110 of the rigid frame 102. The rigid frame 102 has two opposite broad sides, a first side 104 and a second side 108. The first side 104 can be a front facing side and the second side 108 can be a rear facing side. The first side 104 can interchangeably be known as the first side, the front side, or the front facing side. The second side 108 can interchangeably be known as the second side, the rear side, or the rear facing side. The rigid frame has a height “H” and a length “L”. The rigid frame can have a nominal height “H” of 185 mm and a nominal length “L” of 185 mm. The first side 104 and the second side 108 define a thickness 116 of the rigid frame 102. The thickness can also be denoted as “T”. The rigid frame can have a nominal thickness “T” of 12 mm.

The first side 104 and the second side 108 can be parallel. In some cases, the thickness 116 can differ in one region of the rigid frame 102 from the thickness 116 in another region of the rigid frame 102, as shown in FIG. 5A. FIG. 5A shows a rigid frame 502 having a foreground 512 and a background 514. The recesses 110 have a flat bottom surface 128 as shown in FIGS. 2A and 2B. There are no passages or holes in the recesses between the first side 104 and the second side 108, i.e., on opposite sides of the broad sides.

The non-recessed surface (the first side 104 and the second side 108) of the rigid frame 102 can display graphics 126 associated with the respective arrangements of the pieces. The graphics 126 can be displayed on either or both of the foreground 512 and the background 514, as shown in FIG. 5A. The graphics 126 can be a solid color, multiple colors, or a pattern. The graphics 126 can be applied to the first side 104 and the second side 108 by various means. For example, the graphics can be painted, stained, etched, carved, burned, laser engraved, stamped, or glued. On the first side, for example, the graphics can be a brown color representing a surface of the Earth. For example, the graphics can be a rock pattern representing a surface of the Earth. For example, the graphics can be both a brown color and a rock pattern representing a surface of the Earth. On the second side 108, for example, the graphics can be a blue color representing an ocean. For example, the graphics can be a wave pattern representing the ocean. For example, the graphics can be both a blue color and a wave pattern representing the ocean.

The rigid frame 102 can be constructed from wood, plastic, or metal. The rigid frame 102 can be a solid wood. For example, a solid wood can be beech, maple, pine, walnut, or basswood. The rigid frame 102 can be constructed of a composite wood. For example, a composite wood can be a plywood or a medium density fiberboard. For example, the polymer or plastic film can be acrylonitrile butadiene styrene (ABS), polypropylene, or polyethylene. The rigid frame 102 can be constructed of a bio-based polymer. For example, the bio-based polymer can be based on sugar cane or corn. The rigid frame 102 can be constructed of a bio-fill polymer. For example, the bio-fill polymer can be filled with bamboo or rice. The rigid frame 102 can be constructed of a rubber. For example, the rubber can be thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), or silicone. The rigid frame 102 can be constructed of a metal. For example, the metal can be aluminum or steel. The rigid frame 102 can be constructed of a ceramic.

As shown in FIGS. 1A, 1B, 2A, 2B, and 3 , each broad side (the first side 104 and the second side 108) of the rigid frame 102 defines multiple recesses 110. Multiple recesses 110 define an arrangement of the pieces 106. Referring to FIGS. 2A and 2B, the first recess is 110 a, the second recess is 110 b, and the third recess is 110 c. As shown in FIG. 2A, a recess 110 c can accommodate one piece 106 g or a recess 110 a can accommodate multiple pieces 106 a and 106 b. Each recess 110 is surrounded by one or more elevated surfaces of the rigid frame 102. At least one of the recesses 110 on at least one broad side (the first side 104 and the second side 108) of the rigid frame 102 is configured to loosely contain multiple pieces 106 of the set. The recesses 110 of each of the broad sides (the first side 104 and the second side 108) of the rigid frame 102 are sized to simultaneously accommodate all of the pieces 106 of the set. In some cases, the recesses 110 are sized to simultaneously accommodate all of the pieces 106 of the set with the bottom surfaces 122 of the pieces 106 against the rigid frame 102. In some cases, the recesses 110 on one of the two opposite broad sides (the first side 104 and the second side 108) of the rigid frame 102 are sized to simultaneously accommodate all of the pieces 106 of the set with the bottom surface 122 of the non-planar piece 106 extending away from the rigid frame 102. As shown in FIG. 2B, the recess 110 d has a bottom surface 128 displaying graphics 126. For example, the graphics 126 is the text “FISH”. Referring to FIGS. 8A and 8B, on the broad sides (the first side 804) of the rigid frame 802 has a recess 810 b that extend to a greater depth than another recess 810 a. Referring to FIG. 8B, as shown along cross-section 8B-8B, piece 806 a is accommodated in recess 810 a and piece 806 b is accommodated in recess 810 b.

The recesses 110 of the two opposite broad sides (the first side 104 and the second side 108) of the rigid frame 102 are arranged differently, so as to form respective arrangements of the pieces 106 of the set when accommodated in the recesses 110 described below. The recesses 110 of each of the two opposite broad sides (the first side 104 and the second side 108) of the rigid frame 102 are configured such that the pieces 106, as accommodated, are retained in the recesses 110 only by gravity.

At least three of the recesses 110 have different perimeter shapes. The perimeter shapes can be geometric shapes or organic shapes. A geometric shape is defined by a set of points or vertices and lines connecting the points in a closed chain. For example, a geometric shape can be a square, a rectangle, a circle, a triangle, a trapezoid, or an octagon. An organic shape is typically asymmetrical or irregular and tends to mimic shapes found in nature. For example, an organic shape can be cloud-like or fruit-like. For example, in FIGS. 1A and 1B, piece 106 g is a circle. The recesses 110 have a depth “D”. The nominal depth of the recesses 110 is 3 mm.

Referring to FIGS. 1A, 1B, 2A, 2B, and 3 , the set of removable, rigid, non-interlocking pieces 106 fit in recesses 110 of the rigid frame 102. The pieces 106 are easily removable by hand and are not held in the recess 110 by other means. The pieces 106 each have a flat bottom surface 122. The pieces 106 have a top surface 120. The top surface 120 and the bottom surface 122 define a puzzle piece thickness 124 shown in FIG. 3 . The nominal puzzle piece thickness is 15 mm. In some cases, the top surface 120 of the pieces 106 is flat across its entire extent and void of any recess or protrusion. In some cases, the bottom surface 122 of each piece 106 is flat across its entire extent and void of any recess or protrusion. The top surface 120 can be flat or angled as shown in FIGS. 6A and 6B. Puzzle piece 606 b has a flat top surface 620. The puzzle piece 606 b flat top surface 120 is sized to accommodate the bottom surface 122 of puzzle piece 606 a. Puzzle piece 606 c has an angled top surface 620. The puzzle piece 606 c angled top surface 120 is sized to accommodate a surface of puzzle piece 606 d. In some cases, at least one of the pieces 106 with a flat top surface 120 the top surface 120 is smaller than the bottom surface 122. In some cases, as shown in FIG. 6A the set of pieces 106 includes a piece 606 b with a bottom surface 622 b identical in size and shape to the top surface 620 b of the piece 606 b with the top surface 620 b smaller than the bottom surface 622 b. In some cases, one of the pieces 106 is non-planar on a side opposite the bottom surface 122. For example, as shown in FIG. 6A, piece 606 a has a flat bottom surface 622 a. The opposite side 620 a is a point, creating a three-dimensional pyramid. In some cases, the pieces 106 and recesses 110 are configured such that, as accommodated in the recesses 110, the pieces 106 extend above the non-recessed surface (the first side 104 and the second side 108) surrounding the recesses 110.

Each piece 106 has a perimeter shape corresponding to a recess 110. At least one piece 106 fits in each recess 110. Some recesses 110 are sized to accommodate multiple pieces 106. In some cases, at least one recess 110 of each side (the first side 104 and the second side 108) of the rigid frame 102 accommodates only a single piece 106 of the set.

At least three of the pieces 106 have different perimeter shapes. The perimeter shapes are substantially similar to the geometric shapes or organic shapes discussed above. In some cases, at least one piece 106 of the set has a round perimeter. In some cases, exactly two of the pieces 106 of the set are of identical perimeter shape and size. Each piece 106 can have a solid color, multiple colors, or a pattern substantially similar to those described above.

The recesses 110 of each side (the first side 104 and the second side 108) of the rigid frame 102 are positioned to make an arrangement of the pieces 106. The non-recessed surface (the first side 104 and the second side 108) of the rigid frame 102 can display graphics 126 associated with the respective arrangements of the pieces 106.
